I.

Fig. 8 shows the toe cheek 2 having teeth 2a Which engage the toe holder23. 23 holds the sole of the boot Si down against the cover plate 3,thus 23 takes the place of a toe strap. The toe holder 23 is carried bya plate 23a which is threaded to: receive the screw 23h. The toe cheek 2is slotted at 2b to receive the screw 23h.

As described in connection with Figs. l to 4 guide members 8 areprovided in the path of the heel pulling straps 4, 4' which arepivotally mounted in such a manner that they can be rocked into or outof the path of the heel pulling strap. In order to enable the magnitudeof the diagonal pull to be adjusted the guide members 8, are madeadjustable in the longitudinalv direction of the ski. As shownparticularly in Fig. 'l the guide members l, 8 are provided with anumber of holes 28, one behind the other, through which screws 9, lilcan be screwed into the ski woo-d. According as to whether the screws 9,I are passed through the front, middle or rear one of the three holes 28the guide members l', 3 come to lie more or less near the heel of theboot St, whereby the diagonal pull can be substantially varied.

In Fig. 7 the lower half of the attachment shows the guide member 3 inthe rearmost position and the upper part shows the member l in theforemost position. In order to prevent the members l, 8 from being swungoutwardly too far stops Il', l2 are provided which project into recesses3| of the parts l, 8.

In combination with the heell pulling straps ll, Il there is againpreferably used a resilient strap l5.

In Fig. the dotted lines show the position of the heel pulling member 4in various positions of the guide members '1, 8. From this figure itwill be seen that the diagonal pull can be varied within wide limits.

It will bev understood that any suitable number of holes 28 may beprovided in orderto obtain a large range of adjustability and apossibility of fine adjustment.

It should be understood that various modifications and changes in thedetails of construction and arrangement of parts can be made withoutdeparting from the spirit of the invention and the scope of the appendedclaims.
